Which of these structures carries sperm cells from the testes to the lower part of the

Buffer region
(the region of the curve where pH changes little with each addition of a compound
such as NaOH is the buffer region, a buffer resists changes in pH. The excess acid
region is relevant to a titration of a weak base - strong acid titration.)
The titration curve shows a weak acid - strong base. What does the region in Box B
represent?
Equivalence point
Excess acid region
Buffer region
Excess base region

Sublimation
Osmosis
Osmosis results in a net movement of water across a cell's selectively permeable
plasma membrane. When osmosis reaches equillibrium, there will be more water
molecules on one side of the cell's plasma membrane compared to the other, and
the solutions inside and outside will have the same concentration.
The sodium and water solution insdie the red blood cell is at equillibrium with the
sodium and water solution in which the cell has been placed (blue box). What
membrane transport process has occurred across the cell's plasma membrane?
Simple diffusion
Facilitated diffusion
Osmosis
Active transport
